Claims.

This invention relates particularly to continuous-form stationery adapted for use in duplicating machines provided with a special tear-off blade.

' The primary object of the invention is to provide a simple type of continuous-form stationery in which the forms may be torn on a blade provided with a finger opening, without having the line of separation follow the contour of the open- 10 ing in the blade.

The present application constitutes a division of my Patent No. 1,873,489, issued August 23, 1932.

In accordance with a preferred embodiment of the invention, an autographic register is provided at its front end with a notched tear-off blade,'under which continuous form stationery may be led. The stationery is provided with lines of weakening between the slips which comprise the strips, and the central portion of the lines is wholly cut through so as to bridge the notched portion of the blade. After one set of forms has been separated, the succeeding set may be grasped at the notch of theblade and advanced to tearing position.

The invention is illustrated in a preferred embodiment in the accompanying drawing, in which- Fig. 1 is a broken perspective view of an autographic register embodying the invention; Fig. 2, '3 a longitudinal sectional view, taken as indicated at line 22 of Fig. 1; Fig. 3, a broken plan view of continuous-form stationery for use in connection with a notched tear-off blade; and Fig. 4, a

perspective view of a modified form of tear-off 'blade.

In the construction illustrated, A designates a frame or casing of an autographic register provided with a platen A; B, a cover member affording a tear-off blade; C, yieldingly urged registerpins actuatedby swinging a member C; and D, continuous-form stationery provided with cuts or incisions D'.

The casing may be of any suitable construction,

and fonns a housing for a pack for the con-' tinuous-form stationery. The top portion A serves as a platen and the rear portion is provided with a door 10, which is pivoted to the lower portion of the casing by means of a hinge 11, to

1 permit a stationery packet to beinserted into the '50 casing. A roller 12'is journaled in the side walls of the casing and serves to guide the stationery to the platenv The cover member B is pivoted to the front, portion of the casing by pivots 13 and has an open area 14 to permit writing on the underlying forms.

The lateral margins'1'5 are turned downwardly and serve to grip the marginal portions of carbon sheets 16, which are interleaved with the strips. The rear marginal portion is also turned downwardly and is provided with. a notch 17 to engage a companion notch 17a in the door 10. Guide-pins 18 are mounted on the cover and serve to keep the forms in transverse aligmnent. The front edge of the platen A and cover member B are each provided with a finger-opening or notch 19 to permit the ends of the strips to be grasped.

Register pins C are supported on arms 20 which, in turn, are carried by a rock shaft 21 journaled in' the side walls of the casing. The pins are shown urged upwardly through the openings in the platen and cover by the action of weights 22 on the rock shaft, but of course springs or other means may be used if desired.

The swinging gate member C is pivoted to the casing at 23 and is free to swing rearwardly through an opening in the front of the casing,

which is enclosed by a wedge-shaped housing 24. Slots 24a are provided in the housing to permit a rod 25 to be swung rearwardly with the gate C to. which it is attached, and a pitman 26 links the rod to a rock-shaft actuating arm 27.

The continuous-form stationery D may be storedwithin the casing in any suitable manner,- such as in rolls, but preferably it is folded zigzag to form a packet as illustrated in Fig. 2. A plurality of strips may be folded together in vertical alignment with the folds of each strip inter-engaged with those of the others forming superposed sets of slips connected end-to-end. The slips are provided at spaced intervals withv register perforations 28 adapted to be engaged and aligned by the register pins C. The perforations are disposed in rear of lines of weakening 29 so that when engaged by the register pins the lines of weakening will be in alignment with the tear-off edge' 30 of the register. The lines of weakening are interrupted by the incision or.

slit D, which is cut to bridge the gap 19 in the tear-off blade. The lines of weakening, while desirable, are not essential. Ordinarily the lines of weakening are at the folds in the packet. It j and the pins, accordingly, bear against the lower surface of the paper until they find the next set of perforations. The pins not only serve to register the superposed slips, but they also hold the stationery while the advanced forms are severed by an upward jerk. The tear will follow the blade to the notch'and then jump the gap in the blade, due to the incision D. The operation is so simple that it can be performed with one hand without difliculty.

For the purpose of illustration, the stationery has been shown in connection with an autographic register, but it will be understood that it may be employed in many other kinds of manifolding or strip-serving machines.

Fig. 4 illustrates a modification in which a blade 30 is an independent member provided with a handle 30a and a notch 31. The blade may be pressed against the stationery during a tearing operation.

The foregoing detailed description has been.

given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

I claim:

1. Continuous-form stationery comprising a plurality of record-strips, eachstrip comprising a series of record-slips connected end-to-end, the junction lines being transverse lines of weakening extending from edge to edge of the strip, but interrupted by a central slit adapted to bridge the space of a finger-opening in a tear-off blade, the record-slips being in registering sets of superposed slips and being provided in their front margins with register-perforations, the registerperforations of each set of slips being in general registration with each other.

2. Continuous-form stationery as specified in claim 1, having the plurality of strips folded zig-zag at said lines of weakening to form a packet.

3. Continuous-form stationery comprising a series of record-slips connected end-to-end, the junction-lines between record-slips being transverse lines of weakening interrupted by a centrally disposed transverse slit adaptedv to bridge the space of a finger-opening in a tear-off blade.

4. Continuous-form stationery comprising a series of record-slips connected end-to-end, the junctions between record-slips being weakened only by a centrally disposed transverse slit adapted to bridge the space of a finger-opening in an associated tear-ofi blade.

5. Continuous-form stationery comprising a series of record slips connected end-to-end, the junctions between record-slips being weakened by a transverse slit adapted to bridge the finger notch in an associated tear-off edge.
